Here are a few ways to rewrite the title in a formal, professional tone:
Option 1 (Direct and polished):
UNESCO and the Art for Humanity Foundation Launch ‘Youth Creative Lab’ to Combat Misinformation
Option 2 (More institutional/formal):
UNESCO and Art for Humanity Foundation Establish ‘Youth Creative Lab’ to Address Global Misinformation
Option 3 (Concise and journalistic):
UNESCO Partners with Art for Humanity Foundation to Launch Youth-Led Initiative Against Misinformation
Recommendation: Option 1 is the most standard and professional choice for a formal publication.
